# Circuit Playground vs RaspController

The clearest difference is price: RaspController at Free against Circuit Playground's $2.99. RaspController also leads on rating (4.6 vs 4.3). Circuit Playground's advantage is in-app purchases (none vs 3) and ads (none vs shown). On review sentiment, ratings volume, update cadence and device support there is nothing between them.

RaspController is free to download; Circuit Playground costs $2.99 up front. RaspController sells 3 in-app purchases, starting at $1.99 per 3 months. Circuit Playground asks for nothing beyond the download.

RaspController holds the better App Store score, 4.6 against 4.3. Both are backed by a comparable volume of ratings — 19 and 56 respectively. Written reviews complicate that: 86% of Circuit Playground's written reviews are positive against 79% of RaspController's, so the app with the better star average is not the one people write more warmly about.

Circuit Playground ships an update every 6 weeks, RaspController monthly. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
